I'm trying to reproduce this issue, but until now, I've been unable to
reproduce it. I tried some different scenarios with the following
components:

1. Displays: I tried with one and two displays
- 4k@120 - DP && 4k@60 - HDMI
- 4k@244 Oled - DP
2. GPU: 7900XTX

The issue only reproduced with RDNA2 (6900XT)
RDNA3 (7900XTX) is not affected.

Hmmm, again this looks stalled -- and the regression report is 6 weeks
old by now. :-/ Or was a solution found in between?

I'm okay with reverting the patch, but I want to see the requested data and tests first. I could not reproduce this issue on my side, and others did not see it either. I suspect this is something related to firmware or it is a display-specific issue, that's why the data/test that I requested would be useful.

Thanks
Siqueira


So I assume no solution will be ready in time for the 6.10 final? I also
assume a "simple" temporary revert is not a option or bears big risks?
